What does salt do to your brain?

The FDA has found that the average American ingests 3,400 mg of sodium per day - 1,100 mg more than the recommended amount.

In the past, high sodium intake has been linked to hypertension and heart problems. Now, a study done in Québec has brought attention to the effects of differing sodium levels on the brain.

In the study, the researchers examined the association between sodium intake and cognitive function in the brain. They found that low sodium intake corresponded with better cognitive function, predominantly in adults. As more and more people increase their sodium intake, the study concluded that this can have significant public health implications.

Dr. Andrew Gordon, a neurologist with Advocate Condell Medical Center in Libertyville, Ill. and Advocate Good Shepherd Hospital in Barrington, Ill., says "sodium is important because sodium channels are involved in neuropathic pain, seizures and possibly migraines, as well."

Since low or high levels of sodium have been seen to have a "profound and acute effect on brain and nervous system function," it is imperative to maintain recommended sodium levels.

Dr. Gordon says over the past 30 years, researchers have recognized the importance of sodium function, and this has led to breakthroughs in advancing neurological treatments. In Dr. Gordon's opinion, "this aspect of human biochemistry will continue to be important for future treatments, as well."

The FDA offers the following tips for managing your sodium levels:

Carefully read the sodium content on nutrition labels and plan your meals accordingly.Use herbs and spices to season your food rather than salt.Limit the consumption of high-sodium foods such as canned goods and processed foods.Our body is our home, and we need to keep it healthy; say "Na" to salt, and you'll help keep yourself healthy in the long run.
